Brooklyn, New York-based Approved Oil reported the successful performance of renewable diesel supplied to New York City agencies throughout one of the most severe winter periods the region has experienced in more than 65 years, including operations of the New York City Department of Sanitation (DSNY) powered by renewable diesel.

The update follows Approved Oil’s initial announcement several years ago supporting New York City’s adoption of renewable diesel as a lower-carbon alternative to ultra-low sulfur diesel (ULSD) under city procurement and climate initiatives.

This winter’s sustained subfreezing temperatures provided an unprecedented real-world operational test of renewable diesel-powered municipal fleets and equipment at scale.

Despite prolonged cold weather, elevated demand and challenging logistics conditions, renewable diesel supplied by Approved Oil powered DSNY snow response, collection vehicles and critical sanitation equipment without interruption, with no weather-related fuel disruptions reported.

“This winter was a real-world validation of renewable diesel under extreme conditions,” said Vincent Theurer, CEO and president of Approved Oil.

“From both a procurement and operations standpoint, renewable diesel performed exactly as required—delivering emissions reductions while maintaining the reliability and resiliency essential to city operations,” he added.

Approved Oil’s performance was supported by dedicated staff working around the clock, more than 75 drivers and operations personnel, and an exceptional terminal-management team maintaining continuous supply across three states.

In addition to supplying renewable diesel, Approved Oil successfully managed significantly increased demand driven by natural-gas supply constraints and power interruptions, supporting some of New York City’s largest and most critical facilities—including major hospitals, universities and large-scale residential complexes, as well as other mission-critical residential and commercial properties.

Approved Oil said it continues to support New York City and other public-sector customers with renewable diesel, ULSD and blended fuel solutions, while expanding infrastructure and supply capabilities to meet growing demand across municipal, transportation and industrial sectors.
